本文详细描述了用于80~370 K温区内精密测定固体和液体物质热容的自动绝热量热装置。其中热屏绝热控温和样品加热计时均实现了自动化,全部操作可由一人单独完成。通过测定国际量热学会议所推荐的两种标准物质α-Al2O3和正庚烷的热容,证实了装置的可靠性;在全部实验温区内本文结果与美国标准局数据符合在±0.30%以内,测试精密度为±0.04%。

An automatic adiabatic calorimeter for heat capacity measurements of solids and liquids in the temperature range 80-370 K has been constructed.In this apparatus the shield temperature control,the electrical energy input and the heating interval measurement are all carried out automatically.The automatic control permits oneman operation of the apparatus.
